The difficult part about getting a handle on your ventilation system is that air is
invisible. In a big barn, it’s hard to see what’s really taking place. Dale Ricker, swine
program specialist with Ohio State University Extension, and his colleagues have
made it easier to visualize this problem. He and his team have built a trailer that uses
smoke to let farmers see up close how to improve their systems. Ricker’s goal is to have farmers walk away with the skills to make improvements to their own ventilation systems and experience better performance.
